Appncaanfna August 7, 1891. seatinqjmieve. (No modem A Be it knownthat-I, SATTERLEE ARNOLD, a

citizen of the United States, residing at Brook-l lyn, county ofKings,and Sate of 'New York, have invented certain new and useful.Improvements in Sewing-Machines; fully described and represented in thefollowingspecification and the accompanying drawings,

forming a part of the same."

This invention relates to sewing-1nachines, .and especially to'thatclass of machines in which lthe work is carried by a wheel provided withpins or points on which the work is iinpaled, the object of theinvention being generally to improve the construction of this class ofmachines, and especially to provide a maf chine for uniting knit fabricsrequiring less skill on the part of the attendant and by which the workshall be done more rapidly and with less labor and a close smoothseam-be secured without employing the slow and expensive process ofregistering-loops, as in tlie looping` or turningoff machines in commonuse for A uniting knit fabrics.

In'l carrying out. my invention l employ a large wheel providedWitiipins or points, upon which `the work is impaled and by which itisadvanced, and I combine therewith an im` paler by which the work isautomatically pressed O11 .the pins before the sea-m is made,

` it being necessary for the attendant therefore onlyto stretch theworl; upon-the impaling pins tothe desired tension and .secure it atytwo points on the pin-wheel, the proper position of the work for sewingas the different partssuccessively approach the needle thus beingassured wit-hout care on the part of the operator.` tVith-tliispin-wheel and impaler l preferably combine a trimmer, by which theexcess of material above the'l seam rey moved, preferably. after theseam is made, and- 'means` for uncurling the edges of vthe fabric, so asto automatically secure the proper position of the edges of the fabricfor trimmingA and sewing. l provide also a rubber, scraper, or na-pper,by which the edges of the fabric are rubbed, so as to removeany loosematerial and raise vla. napuuponytlie edges, and. a sheaiger, by whichtliejnapraisedby the .rub-rn ber isvtrimmed off, soas *topa/idinformingfa srnoothernished seam.

erably rotated continuously, as fully pointed I out hereinafter, andcertain constructions, in-

cluding such a continuously-rotating wheel, in combination withotherfeatures, form parts of the invention independently ofthe impaler, asWell as improved devices yforming parts of the machine embodying thegeneralfeatures of the invention in their preferred form.

With the pin-wheel and Leo-operatingde-l vices above described I mayemploya sewing mechanism-of any suitable form for uniting isevidentithat the wheel and co-op'erating devices may be applied tomanyof the forms ofV such mechanism now in use. I prefer, how-v ever,.touse a sewing mechanism-of substan` ythefabrics without registry of theloops, as ,it-

378,6et5, dated February 28, 1888, in which the v needle-bar has amovement in the line of feed n when the needle isout of the work, so asto form a retrograde stitch. A

For a full understanding of my invention a 4 detailed description of amachine ofthe pre'- ferred form embodying the same1 will now be.

given, reference being had to the accompany'- ing drawings, formingapart of-.this specification, in \vhich,- I y V Figure l isa sectionalfront-elevation of the machine.

Referring 4to said drawings, themf'rameof the machine consists" of thebed-plate A, upon which is' mounted the overhanging frame B,

extending toward .the front of the machine,

where it is provided .with two'depending arms QD, the for'mersupportingthe sewing mech- -anis'm'andftllfelatter the feeding or pinwheel and'colo'perating' devices, which are located ing frame Bat such a distancefrom the-'bed-l plate'A as tolte ontsidefthelattemfso that the The partstowhich my 'inven'tion*especially relates will first' be described indetail The pin-wheel E consists of a large' .'whcelprefenI ably arrangedhorizontally and providedbn `its periphery-near the upper edgejwith fa'sework may 'readily heplacedupon and lcarried ries. of -radial pins 10, extending preferably through. the whole or a large lpartofthecircumference ofz the wheel, these pins being set at' any suitable.distance apart, so as to hold -the fabrics't'obe united in'properposition,

'the rim-of the wheel thusforming a pinfplate by which the goods arecarried. 'Thiswheel E is. carried by a vertical shaf t F, monntedinbearings in the arm.D and provided at its upper end with a wormwheel1],.which meshes with a worm 12 carriedby the shaft- G, which` ismounted transverse-lyof lthe machine in bearimgrson the arm O D, thisshaft being driven'from a'vertical shaftH through beveled gears 1.3,,theshaft H being inturu driven -by the-main` operating-shaft of the sewingmechanism IA through worm 1 4 and-worm gear "15." 1 "v The mainoperating-shaft K may be driven in any suitable manner, but islshown asop erated by a belt-and-pull'ey' connection from the main. driving-shaftK, mounted 4in the frame A at the rear of the machine..

-The connections between the driving-sl1aft and `pin-wheel arepreferably constructed to be'broken at' will, so that the latter 'may bethrown out of operation.. Any suitable means may be provided for thispurpose. I have shown a simple construction vin which the shaft G iscarried by a slotted bar 16, sliding 'on the-.head of the machine andheld in position'with the 'worm 1'2 in engagement with theI gear -lLbyspring 17.. T-he plate 16 is movedagainst the tension ofthe-spring 17 tolthrowthe worm. and gear out Aof mesh by a pin 18, acting within thecam-slot 21, formed inthe plate 16,v said pin beingcarried on a verticalstud orshaft20, actuated bya hanf die 19.

For thel purpose of automatically pushing the'work onto theimpaling-pins, so that it is held` firmly in proper position as itl ap-lproaches the needle, I provide an impaler,

which engages the wjork,"preferably upon` 'both sides of'theimpalingf-pins, and forcesit upon and down to the base ofthe pins, sothat it. is held in proper position for sewing. This impalerispreferably of the formshow xnconsisting of `a head 22,.,slotted so as toengage 4 cam-groove.

23, sliding in supports in the arm C and pivotally connected at itsfrearend to an arm 24 on a-vertical shaft'25,'inounted in bearings onv therear side of the arm C, this shaft 25 beprovided with abowl or rollerrunning'in the The impaler. is preferably provided with a curved orinclined guiding-sur- `face on the side from 'which the wot-kap,

proachestheimpaler, so that the work is properly deflected or guided anddanger of its catching'as it passes the impaler is avoided. .As shown,lthe impaler iscurvedon the oppositeside also; but-'this is notimportant.

. While I prefer to use an impaler moving to 4 by a reciprocating head,vas shown in Fig. l,

may be found satisfactory.'

A trimmer is preferably mounted above the wheel on'thejopposite side ofthe needle from the impaler, and 4is constructed as follows:

The trimmer proper consists'of two rotary' cutters 28 29, carried,respectively. by shafts '-3031, connected by gears 32, so that theshaft- 30 is driven from the shaft 31 and preferably at ahigher rate ofspeed, as shown, so as to make a drawcutj The shaft 31 is driven bymeans of a pulley 33 and belt 34 from a sleeve ,ing operatedbyaGaIn-groove 26 in the upper tidejof: the Worm-gear 15' by a crank-arm27,

.and from the pin-wheel a Stationary ilnpaler may be used, and 'it isevident that the form 9 of the impaler may be varied widely..v Thus,

35, mounted loosely on theI shaft Fof the wheel E, this sleeve beipgdriven by any suit,- able means, preferably from the drivi ngshaft K-bya'pulley 36and belt 37,' as-sho'wn.'

The' rotary A cutters andv4 their operating mechanism maybe mounted ina' fixed position upon the frame'of vthe machine in--any suitable'manner as such cutters are commonly mounted; but, for apurpose presentlyto be described, I.pref.er. to mount them, as shown, inaswinging-bracke'tBS, carried by a sleeve 39 'on shaft Einside thesleeve 35,. previously described.A This swingingfbracket with thetrimmer is-held in the proper posi. ytion by means 'of an. arm 40 on thearm D, provided withI a pin 41,' adapted to hold the latter in place,this arm 40 b'eing preferably made movableve'rtically upon the arm D bya slot and set-screw 42,-as-'s'ho'wnin Fig. 3, so' that the pin may b ewithdrawn to release -the bracket; 38 and'allow vit to be swung .uponthe s and releasing 'the bracket.: fIhe arm .4Q may.4

ft F. Anyzotherconstruction-,may be.` used,l owever, for the purposeofisecurin'g be a strong spring-arm secured in a yfixed po-- sition onthe arm D, but which may be sprung upward to release the pin when thebracket is to be moved.

The bracket 3S-,is supported outside the shaft F by a bowl or roller 43,moving freely upon a rib 44 upon the upperside of the pinwheel E,`thisbowl 43 being preferably made adjustable by a bolt and set-nut 1, as'shown,

so that the vertical-position of the bracket and trimmer may beadjusted, as desired, to secure the trimming of the seam on the properline. The shafts 30 3l and cutters 2S 29 may both be mounted in fixedbearings in the bracket 3S, as such cutters arecommonly mounted; but,for the purpose of adjusting Athe lap of the cutters to secure theproper action and compensate for wear I prefer the construction shown,in which the shaft 3l is mounted in a fixed bearing 45, secured to thebracket 38, and the shaft 30 is mounted iu a hearing 46,`adj ustable asfollows: The bearing 46 is supported by an ear-47, carried therelby andadjustably securedto an ear 48, carried by the bearing 45. Theadjustment is secured by a pivotal connection at each vend of the earsformed-by three screws, the upper screws 2 at each end beingl threadedin ear 47 and resting in recesses in the adjacent face of ear 48, so asto form pivots on which the bearing 46 swings rin a vertical plane,these pivot-screws being` preferably in line 1 with gears .32, so thatthe'meshing of the latter is not affected by the movement of bearing 4G.p The lower adjusting-screws 3 also are threaded in the ear47 at each,end and rest on the surface of ear 48. The central adjusting-screws4,between screws 2 and 3, are tapped through and loose in ear 47 andthreaded in ear 48. j

, By withdrawing screws 3 and tightening screws 4, or vice versa, thebearing 46 may be swung on pivots 2 and any desired adjustment ofthe'lap of the cutters secured. It

.is desirable also that a vertical adjustment should be provided by.whicbthe distance between the cutter-blades maybe varied, so as tosecure the proper contactpressure. For this purpose I provide the meansshown in detail in Figs. 7 and 13. y The `shaft 30 is mounted to slidethrough ythe bearing 46-aud The hub Vttof gea-r 32 carries twoadjusting-screws 7v 7', which `are tapped through the hub 6 fromopposite sides and,-

engage the upper andlower sides ofv grooves or recesses 8, these sidesbeing beveled opy posite .directions to form cam-surfaces, where theyare engaged by the screwsl7 -'The shaft and gear are held against upwardmovement during the operationof the cutters by',

the bla es, and the shaft is adjusted. vertically todpress thecutter-blades together and compensate for wearl by loosening the screws7 and tighteniugthe screw 7. By reversing this-loosening the screw] andtightening ine screw 7the pressure .maybe decreased tud thus an exactadjustment obtained. l

The surplus material above the seam removed by the trimmer is thrownoft' by a shedder formed of twolplates 49 50, mounted just above thecutters 28.29 and extending in the line of movement of the pin-wheel andoutward from its periphery. These plates 49 50 are secured to the ear4S, previously described, by screws '9, as shown, or in any othersuitable manner, so that the shedder may readily be removed. The plates49 and 50 are extendedon rthe opposite Sides of the cutterblades, so asto form guides between which the edges of the fabrics are held as theypass t0 the cutters, these guides 99 100 forming au uncurling device bywhich the curling or turning over of the edges of the fabric above theseam is prevented and the proper presentation of the fabrics to thetrimmer secured. An'uncurling device is preferably used in connectionwith-the impaler and sewing mech- `anism, and may be found'suflicient toprevent.

the curling atthe trimmerwithout the use of the guides 99 100, justdescribed, this consisting, inthe construction shown, oi' a plate 101,placed edgewise j ust-above and parallel with the wheel, opposite to ora little behind the impaler, and lhaving an inclined surface operatingto uncurl the edges as the fabrics approach the impaler and sewingmechanism.

As above stated, I prefer to place the trimmer in the position shownV infull'linesin' the y drawings, so as to'trim oif vthe surplus portion ofthe material after the seam is made; but, if preferred, the trimmer maybe placed on the otherside of the needle and the surplus ICO materialtrimmed ed before the seam is made.

My improved trimmer mounted to swing concentrically with itsdriving-shaft is adapted to be used in either position, and for thepurpose of securing it inadvance of the impaler I have shown an arm 5l,provided with a pin 52, similar to the arm 40 and pin 41, previouslydescribed.l the arm 5l being mounted upon the arm D by a slot-and-screwconnection 42, as in the case of arm 40, but extending in theoppositedirection from arm 40, so 'as to hold the trimmer in positionupon the opposite side of the needle. This arrangemeut of the trimmer isshown in dotted lines in Fig. 5. As it is necessary that vthe fabric beimpaled upon the pins before trimming, the impaler is mounted inadvanceof they trimmer, Vand when the trimmer is positioned as justdescribed, so as totrim-before the seam is made, I may employ a'stationary impaler, as previously described, and mount it upon thetrimmer-frame,l as shownin dotted lines inFig.5L` f When the trimmer isto be secured inv position in advance of the needle, the shedder 49 50must be removed; but a shedder of simila'rform may be secured upon theoppositeend ofthe plate 43', so as to guide the surplus material'outwardl from the pin-wheel, as shown- It .will beseen from thedrawings that to swing ,the vtrimmer it is IIO necessary only toremove'the pin 4i, solas to ryelease the trimmer andpto remove the bracke`by'ltiihich the rubber and shearer and their op erating parts, to bedescribed hereinafter, are daifried.

For the purpose ofrnbbing down the s eam, removing -the surplus materialleft by the trimmer-such as' any loosecut lo'ops of-'knit goods-andraising anap upon the edge of the united fabricsi pro'videa rubber,scraper, or napper, which consists, preferably, as shown, of two or moreknife-blades,which are provided with'teeth ontheir under sides, whichengage -the edges of the fabrics. The'knifeblades 5,3,forming therubber, are carried by an arm 54 on .a shaft 55, mounted on screws'pivot bearings 56 in a bracket 57, carried. by the arm B andremovably'secured thereto by screws 58, or in any other suitablemanner.' The arrnft is preferably adjustable ou shaft 55, as shown, soas to secure theproper action oi'therubber. The shaft 55 is rocked bya.4 crank 59 and pitman 60 from acrank-disk 61, drive'ufromthe maindriving-shaftK or other part ot the mechanism in any suitable manner. Asshown, th'e disk forms a pulley and is driven by a' belt 62 fromtheshafb K.

MVhile I prefer to form the rubber of toothed blades, as shown, itisevident that its construction may be varied. Abrush of'any suitableconstruction or a iile maybe used with good results,- but thisconstruction is' preferable both on account of the better resultproduced and the ease with which the toothed blades are kept in propercondition. The movement, also, may be varied and a notating'rubber employed,vvvhichv may be of any suitable form and operated by any of themeans in common use with rotating brushes' in looping-machines, but thereciprocating rubber is preferred. l

The long'nap raised bythe rubber is preferablytrimmed off to form asmooth and in "ished-inner edgeof the seam, and for this purpose Iprovide a Shearer, which consists, in the formshown, of an oscillatingblade 63, carried by the shaft 55, previously described, so as tooscillate with the rubber 53 and act upon the fabric just after thelatter, this blade 63 (Jo-operating with astationary'blade 64, munted onthe base-plate A.

Referring especially to Figs. 1, 3, 4,5,'and 10, this sewing mechanism will now be described. The mainoperating-shaft I, previonslydescribed, is supported'in the upper partof the arm G,'and is provided at its inner end witha crank-disk 67,connected by' a'link 68, withone'of the cranks 69 of the crank-shaft7.0, the'` other crank .71 of which4 is connected by means of a link 72withthe upper end of the looper-rod 73, which carries at its lower endthe looper by which the needle-thread is carried/around the stationaryshuttle 74.' This construct-ion is substantially that of my Patents Nos.331,006 and 331,007. The looperLrod is provided near its middle nut inany position towhi'ch it may be ad-V justed inthe bridge-piece 75, thehead of the -stud beingslotte'd to permit its adjustment bya'screwdriver.

A vertical shaft 90 isv mounted on the rear side ofthe arm C, adja- 'the thread are of a common constructiion cent to theshaft 25, and is oscillated'by means of a crank-arm 91, having a bowlrunning in a cam-groove on the lower side of the Worm-gear 15, all asshown in Figs. l, 2,'and 4. This shaftI 90 carries at its lower end aslotted roclg-armx92, in which a pitman 93 is adjustably\securedv bymeans of set-screw 94,' this pitman ,93 being secured at itsoppositefend to `vthe needle-bar'frame 80 by a p ivoted ad- ]'ustableconnection 95, as shown in Fig. rl0, so th-atvthe throw ofthe needle-barframe may be varied by adjusting the pitman 93 in the slotted rock-arm92 without changing the central position of the needle-bar frame. The

The special form of voperatingmechanism,v

thedevices for guiding the looper-rod, and the connections for swingingthe needle-bar frame form no part of the vpresent invention, but are ofsubstantially the construction claimed in my application `above referredto.

Theoperation of the machine, so far-as it involves the features of myinvention, will be understood from a brief description inv connectionwith the drawings, especially Fig. G.

f The fabrics to be united are placed upon the pin-wheel E by securingthe advance end of the fabric to the pins slightly in advance of theimpaler and then stretching the fabric to the desired tension andsecuringthe fabric to the pin-wheel' upon theopposite side of the wheeljustin advance of the shedder G6, or at any point, desired,in'accordance 'with f vthelength of the fabric tobesewed. lf the -workconsists in sewingl together knitandf4 woven fabric or fabrics o fdifferent elasticity,

as to secure the desired tension and relation them and hold them inplace for the impaler, which presses lthem upon and downto the base ofthe pins as they are advanced-toit byA the pin-wheel, so that the properposition of By the use together, and preferably substantially as shown,l am able to properly support knit and other 'elastic fabrics and holdthem in vproperv As before stated, the nee-` position throughout, sothat the lines of sewing and trimming may be formed on' true right orcurved lines, according to the manner in which they are placed upon thewheel, and the edges may be trimmed closely to form a fiat seam.' lf thepins fare placed wide apart, the fabrics will not be supported properly,but will sagbetween the pins, so that the lines of sewing and trimmingwill. be irregular when the fabrics are removed from the wheel. .Theexact distance apart at which the pins are set will vary'somewhat withthe character of the goodsbutwith the common knit goods it will be foundthat.l the best results are attained by setting the pins at a distanceapart of from' a' sixth to a half inch, although this distance may beincreased somewhat with fairly good results. In placing the fabrics uponthe pin-'wheel no attion thus differing essentially from the ordinaryloopingmachine, in which the points. are so arranged thatsuccessiveloopsare impaled upon the points and the movement of the needleregisters with the points, so that it. is necessary to provide differentmachines for fabrics of different, mesh. My vmachine Ais adapted tov sewfabrics of any mesh, the

range of adjustment of the stretch being unlimited, it beingnecessaryonly to secure the' ends ofthe fabric to the pins so that vthe fab-Ii'ie will-be held in properfposition, andthe operatoris not required toimpale the fabric upon each one of the pins in proper position forsewing, as this is automatically done by the impaler. proved machine, inwhich the fabrics are unit-ed bysewing withoutregistry of the loopsinsteadof by looping, I am ableto use with knit fabrics a feedingmechanism haw.

As the seam is formed and Athe fabric X fed forward past-the needle. Thesurplus material Y kabove the edge of the pin-wheel is trimmed off by,the cutters 2S 29, formin'gthe trimmer, and theshedder, formed ofthepl'ates --LG 50, guides the surplus material fromt'he cylinder as itis trimmed olf, all this operatio'n being shown clearly in Fig. 6. AfterThe work having been y passing the trimmer the edge of the unitedfabrics acted upon by the rubber, so as to knock on i: any lcose half orcut loops and nap up the ti 3er, the material being held in po- .sitionduring this operation by the curved guide G5. 'ihe operation of thisrubber dif fers essentially from that of the brush now in common use inioopinginachines`,in which the brush does notlact as a napper, becausethis is im pcssihle without risk of injuring the registeredv loop, thebrush simply operating tc remcve the outside broken loop withoutaffecting the fabric. In my machine, in which knit fabrics are united bysewing without regi try of the loops, as distinguished from Theoperation is the same with the trimmer adjusted to the opposite side ofthe needle and heldin position by the arm -inadvance of the needle orswung above the wheei to trim prior to sewing, the surplus material thenbeing removed before the sea-m is made, the rubbingand shearingoperations remaining the same.

The operation of the needle will be understood from a brief generaldescription. The

stitches are set so closely together thatl the' vmovement of 'the workwhile theneedle is within the same is very slight, so that a continuousfeeding movement is possible, even withgo'ods' of close mesh, and thestitch is forme'djand the fabrics secured together just abcve the pinswithonn-fregistry of'the loops as he worl. is carried gast the needle bythe pi v. wheel. Vtlith ne retrograde .sewing mechanism shown, inwhich'a seam is formed a combined open stitch and short gripntitch, asfully set forth inv my Patent No. 378,645, the work is carried past theneedle by the pin-wheel to form v the open stitch. When the needle iswithdrawn from the work at the completion of this stitch, the swingingneedle-bar frame will be actuated by the connections heretoforedescribed, so as to carry the needle a short distance in the directionof the feed, thus forming a short retrograde gripstitch, the needle thenbeing returned to nor- 'mal position when withdrawn from the work andanother open stitch being formed. The pinfwheel, in combination withtheretrograde movement sewing mechanism, provides a positive feed, and I amable to secure the proper function of the retrograde stitch and form amuch closer seam than otherwise. I am thus able also to use theretrograde stitch with knit fabrics without employing a looping-cylinder, and this -stitch serves to form astrong,

tight seam, irrespective of the line'on which Ithe knit fabrics are cui.

It will be seen that the pin-wheel is driven by the wormgear 11 and worml2 by a slowmovcm'ent relatively to the sewing mechanism, and this formof feed enables the movement of the pin-wheel to be readily varied inthe construction of the machine,.as desired, and a rslow speed attainedwithout a. complicated gearing. y By means of the handle 19 and slidingplate- 10 the driving mechanism forthepin-wheel may readily and quicklybe thrown out .of operation when desiredfor anypnrpose.

lt Wli be understood that I do uottliniit myself te thespecitic form ofdevices shown, as many modiiications'may be made therein withoutdeparting from my invention.
